SLIIT M.A.S.T.E.R.M.I.N.D Group had uploaded the past papers to a free file sharing website and had published the downloading link on facebook. The capacity of that file was around 11 MB. So I download that, separated the files and uploaded back to mediafire. So that those who are having slow internet connections can download only the required past papers.
Download 2002 to 2007 past papers. (1.71 MB)
Download 2008 past paper. (3.14 MB)
Download 2009 past paper. (940.12 KB)
Download 2010 past paper. (5.42 MB)
My advice for the freshers is that you don't need to do all the past papers to get good results. The papers of last two years would be more than enough.
Good Luck with your exams.
